Abstract
【解決手段】 複数の反応管と、反応器シェルに導入された熱媒の移動方向の変更が可能な邪魔板と、該熱媒が該邪魔板の面方向に流れる部分の一部に設けられた、該反応管を配列しない空間部と、該空間部と該反応管との間に設けられた、該反応管と同一の長手方向を有する整流棒群と、を備える接触気相反応用多管式反応装置に関する。整流棒群は空間部と反応管との間に1〜10列の範囲内で配列されることが好ましい。また整流棒群として、該反応管に触媒が充填されていないダミー管が配列されることが好ましい。本発明の接触気相反応用多管式反応装置は塩素ガスの製造において特に好ましく使用される。
【選択図】 図1
Description
以下、実施例を挙げて本発明をより詳細に説明するが、本発明はこれらに限定されるものではない。
図1に示すような多管式反応装置1における反応器シェル109内の熱媒流量についてシミュレーションした。図5は、本実施例のシミュレーションにおいて採用されたバッフル(邪魔板)の形状を示す図である。切り欠き部51を設けた邪魔板5を貫通するように反応管52および整流棒群53が設けられている。なお本実施例においては、整流棒群53が空間部と反応管52との間に1列に設けられている。
内径:450mm
バッフル(邪魔板)間隔:277mm
(バッフル(邪魔板))
胴内径W1:450mm
バッフルエッジ長さW2:306mm、
反応容器の中心線からバッフルの切り欠き部までの距離W3:165mm
厚さ:6mm
(反応管(反応チューブ))
外径:21.4mm
ピッチW4:29mm
配列:正三角形配列
本数:158本
(整流棒群)
外径:22mm
ピッチW5:29mm
配列:切り欠き部に沿って1列
本数:11本/1列
(熱媒)
種類:HTS
流量:18m3/h
なお、シミュレーション解析ソフトとして、「Fluent」(米国Fluent Inc.社製)を採用した。
上記のパラメータによるシミュレーションの結果を表1に示す。表1の結果より、整流棒群53が配列された部位においては熱媒流量がマイナスであることから、該部位においては中心線から切り欠き部51に向かって熱媒が逆流することが示される。一方、反応管2列目の部位においては熱媒流量の水平成分が十分大きく、熱媒が正常に流れることが示される。これらの結果より、反応管52と切り欠き部51との間に整流棒群53を設けることにより、熱媒流れの正常な部位にのみ反応管52が配列されることができることが分かる。ホットスポットの生成は、熱媒流れが異常である部位で主に発生することから、反応管を通過する熱媒の流れが正常化された本発明の多管式反応装置においては、過度のホットスポットの生成が抑制されると考えられる。
